- to which it appertains tomake and use the same.

My invention relates to trucks, and more particularly to that class oftrucks adapted for moving houses or other large objects.

The object of my invention is to provide a truck for moving houses whichwill necessitate the house being raised the least possible distance fromthe ground during movement,

thereby reducing to a minimum the cost of moving and also thepossibility of injury to the walls of the house due to twisting.

Another object is to provide a truck having wheels which may be adjustedat any angle to the path of the load, without changing the bolsters orraisingthe building.

A still further object is to provide supportingwhcels for the truckarranged in pairs and connections between the pairs of wheels, wherebyeach pair is allowed to rock or travel in any plane entirely independentof the other wheels.

In the accompanying drawings, Figure 1 is a plan view of a framesupported upon three trucks. Fig. 2 is a plan view of a frame supportedupon six trucks arranged in pairs so as to support an extremely heavyload.

Fig. 3 is a sectional view on the line 3-3 of Fig. 2, showing theconnecting beam between the front pair of trucks. Fig. 4 is a sectionalview on the line 4.4 of Fig. 2, showing the connecting beam between therear pairs of trucks. Fig. 5 is a sectional view on the line 5-5 of Fig.1, showing the extension bolster disposed between the wheels of thefront truck. the line 66 of Fig. 1, showing the extensionbolsterdisposedbetweenthe wheel's of the rear trucks. Fig.7 is aperspective view of one of the bolsters. Fig. 8 is a sectional view onthe line 8-8 of Fig. 1.

Referring to the drawings, in which similar reference characters denotecorrespond ing parts throughout the several views, 1 represents thewheels which are arranged in pairs and mounted in spaced relation uponshort shafts :2, said wheels having disposed Fig. 6 is a sectional Viewon.

therehehveen bolsters- 3 havingv a bore l in the lower portion thereofthrough which extends the shaft 2. The upper portions of the bolstersare provided with slots 5 which extend from the upper surface thereofand taper downwardly, terminating a short distance above the lower bore4.

Each truck is composed of two' pairs of wheels, the pairs of wheelsbeing arranged to travel rearwardly of one another or side by side, andare connected in either'arrangement by means of connecting beams 6. Theends of the beams are bent downwardly to provide fingers 7 which areloosely mounted within the slots 5 of the bolsters 3, while the centralportion of the beam is depressed as shown at 8. The bottom portion 9 ofthe depressed portion 8 is provided with laterally projecting lugs 10,for a purpose which will hereinafter be made more clearly apparent.

The frame for supporting the object to be moved is composed oflongitudinal beams 11, and front. and rear cross beams 12 and 13respectively, said beams being connected by substantially Z-shapedsections of metal 14. Referring to Fig. 1, wherein is disclosed threetrucks for supporting the frame, it will be noted that the front truckhas the wheels thereof arranged longitudinally of the frame, and theconnecting beam 6 which connects saidtwheels is disposed under the frontcross beam 12 for supporting the front portion of the frame, while thewheels of the rear trucks are arranged transversely of the frame and areconnected by the connecting. beam 6, the central depressed portion ofthe latter receiving and supporting the longitudinal beams 11 of theframe. To allow pivotal movement of the trucks beneath the cross beamsl2 and 13, I I

secure to said beams, directly above the horizontal portion 9 of thecentral depressed portion 8 of each connectingbeam, a plate 15 having anopenin therein to receive the stud 16 of a cap 17, t e latter having asemi circular depression in its under surface within which is positionedthe aforementioned lugs 10.- For insuring a rigid connection between thecap 17 and the lugs 10, straps 18 are positioned around the under facesof the lugs 10, and secured to the under surface of the caps 17.

Each shaft 2 carrying the wheels 1 is rovided with a pair of straps 19,to which is secured'the draft and steering pole 20. The

draft poles 20 of the rear trucks are secured by chains 21" to the rearcross beam 13in order that the said rear trucks will be permanentlyadjusted to pursue a path longitudinal to the frame, Whereas the draftpole 20 of the forward truck is adapted to re- 'ceive a suitablepropelling means. I

In Fig. 2 is disclosed a slightly different arrangement of the trucks,and wherein six trucks are employed instead of three, as is Y the numberemployed in Fig. 1. The trucks 'in Fig. 2 are arranged in pairs and areconnected by cross beams 22, having arranged centrally thereon, thelaterally extending lugs 10, the same as those employed upon connectingbeams 6. The upper surface of the beams 22 carries the frame composed ofthe longitudinal and cross beams, while the ends of said beams areprovided with apertured plates 15, as shown at 23, to receive the stud16 carried by the cap 17 the latter being secured to the laterallyextending where an extremely heavy house or other trucks may be employedby the introduction 'of the beams 22, as shown in Fig. 2. It will befurther seen that by the improved supports for the frame, the latter issupported only a very short distance above the, ground, thus enablingthe operators to readily position the heavy object to be moved thereon.

What I claim is p A truck comprising pairs of front and rear wheels, ashaft for each pair of wheels, bolsters positioned on said shaftsbetween said wheels, seats formed in said bolsters having the upperportions thereof elongated on a line longitudinal of the shaft andtapered downwardly, a connecting beam having the opposite ends turneddownwardly and mounted within said seats and having the central portiondepressed, lugs extending laterally from the depressed portion of saidconnecting beam, a cap disposed over said lugs and having an upstandingstud, and straps connecting saidcap with said lugs.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
